Klamath Network Invasive Species Monitoring Data from 2009

The Klamath Inventory & Monitoring program collected data across six U.S. National Parks from April to September 2009. A crew monitored 170 road and trail segments totaling 395 km, recording 225 infestations of 26 invasive species and collecting site-specific data at 152 infestations. This dataset represents the first quantitative sample of all six parks using a repeatable, peer-reviewed methodology.

Use Cases

• Modeling invasive species proximity to infrastructure based on the observation that infestations tended to occur within 6 meters of roads or trails.
• Analyzing habitat preferences of invasive plants based on correlations with overstory cover mentioned in the description.
• Comparing infestation rates between roads and trails based on the finding that they occurred more often along roads.
• Developing early detection protocols based on the repeatable, peer-reviewed methodology used for the first quantitative sample of the network.

Strengths

• Data collection followed a repeatable, peer-reviewed methodology, ensuring scientific rigor.
• Covers 395 km of monitored segments across six distinct parks, providing spatial breadth.
• Records 225 separate infestations of 26 different invasive species, offering taxonomic diversity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single season in 2009; temporal scope is limited.
• Row count is unknown, which may limit suitability assessment.
